Spotify Premium is available in Estonia, Finland, France, Germany, Italy, The Netherlands, Norway, Poland, Portugal, Sweden, Spain and the UK. The Free version is only available in Sweden, Norway, Finland, the UK, France and Spain.

It amuses me to see the adverts briefly appear in last.fm (and permanently in your Spotify history).

Gaps spotted so far: no King Crimson, very little UK Funky, no Aeroplane mix of Grace Jones "Williams Blood" (although their mix of Friendly Fires "Paris" is on there). Remixes are generally well represented, though.

How on earth are they going to make any money out of this model? I can only imagine that once they've got a critical mass of people using it, they're going to radically increase the amount of advertising.

At the moment, the advertising is pretty unobtrusive so I can't see why anyone would want to be a paying subscriber. Which is why I'm guessing they'll up the advertising once they get enough people hooked.

Indeed, at the moment the advertising is infrequent enough not to annoy but I'm sur it'll increase in frequency. Service is good but not quite thorough enough, some bizarre gaps in artist's discographies e.g most of Sparks 70's output and their most recent work but little from the 80s/90s. Once they can plug those gaps, get on board the digital refuseniks and most importantly provide a mobile service then £10 a month would be very tempting.

Can anyone think of a reason why a track would be playable on the spotify client on my home pc but the client on my work pc tells me this track is not available in the US? It's dumb, because home and work are only 8 miles apart and in the same US city.

Most likely two reasons: 1) it's actually not available, but you have it in your local iTunes library at home; 2) your office's network goes through some odd internet routing. If I'm on my work VPN lots of programs think I'm in Sweden.

Also, if you paste in the URI for the track, I can check where it's available.
